Pakistan has summoned the country's US envoy to protest Donald Trump's claim that it harboured Osama bin Laden despite receiving billions of dollars in American aid. The country's foreign ministry said the US leader's rhetoric was "totally unacceptable" and insisted Pakistan's intelligence service provided evidence that helped Washington trace the al Qaeda leader. "The foreign secretary called in the US CdA [chargé d'affaires] ambassador Paul Jones to register a strong protest on the unwarranted and unsubstantiated allegations made against Pakistan," the ministry said in a statement.
